D Will be drawn down rocking the lever arm Y sufiiciently to permit increasing pressure on the carbon pile K and relieving that on K thus producing the usual regu lating effect. The arm X Will be prevented from following the motion of the lever as it rests against the surface or stop R If on the other hand, the load on the source A should decrease below the average for which the spring S is adjusted, this decrease must continue until the decrease in pull of the solenoid H. is suflicient to offset the tension of the spring Q, and permit the spring to to pull the lever D to raise the bar X, and thus increase the pressure on the pile K and decrease that on K thereby causing the battery to charge; the arm Y resting on its stop R It will be seen, therefore, that a certain zone of fluctuations on the source A is established Within which the regulator is held inactive. Whenever the fluctuations pass this zone in either direction, the regulator acts as usual to throw substantially all of the balance of the fluctuations on the battery. The amplitude of tor, a controlling spring for the movable part, a pair of movable arms arranged on opposite sides of said part, a second controlling spring connecting the arms, and a fixed stop for each arm, whereby the action of said movable part is controlled by the algebraic sum of the spring tensions.

In testimony whereof, I have hereunto signed my name.
